1.	Which of the following is correct?(a) If possible, designer should omit unnecessary part to reduce cost(b) Lift is always same as weight of the aircraft(c) Producibility concern should not be used at all(d) Only forging process will affect costThis question was addressed to me in my homework.Query is from Configuration Layout in chapter Configuration Layout Considerations of Aircraft Design
Answer» Right CHOICE is (a) If possible, designer should omit UNNECESSARY part to reduce COST Easiest explanation: By omitting unnecessary parts, we can reduce WEIGHT, material etc. to reduce the weight. Weight is not always same as lift. Producibility concern is used to reduce overall cost. Forging only will not affect cost. Cost is BASED on weight, materials etc.
